installing master cutoff switch

[aafc]

HI,
Since i moved my batt to the right rear storage compartment in my ZR-1
for drag racing i'am also installing a master cutoff switch. The switch has
4 terminals two for the batt. feed and two for the alt.feed.
Checking the FSM section 8 pg 8A-30-1 it looks like i could remove the
alt. output ( s wire ) from the jump start junction block run it back to the
switch and then to the jump start junction block to complete the circuit.
Then when i turn off the master cutoff switch it will remove power from
the Batt. feed and from the alt. output. Or is there diff way to do this.
Thanks
John
